Every programmer when working with databases will use a framework, which facilitates and speeds up development time. It is no different with me. I never liked ADO.NET. Taking out the data and storing it in a DataSet or DataTable that were not strongly typed is not a best idea. Especially when someone else on the later stage had to work with this code and no one actually knows what the author had in the mind writing it. For many years, I enjoyed the heavier Object-Relational Mapping frameworks, i.e. Entity Framework (version 4.0), LinqToSQL (the beginnings of my work as a programmer) or NHibernate.

Every experienced developer knows how important is to cover your code with tests (or at least business logic). However, not everyone likes to do that once code is already written, because, why should we do that? The work is done, it was tested and it functions correctly, right?

I never liked to cover the code with tests once it’s already there. That’s why in this article I’ll present Test Driven Development and describe how I use it day to day.

Design patterns which I would like to present in this post are well described in the book Design Patterns. Elements of Reusable Object-Oriented Software written by The Gang of Four (Gramma, Helm, Johnson, Vlissides). In my opinion this book is must read for every developer, regardless what programming language you are using. Besides the fact that this book was written more than 20 years ago, it still contains a lot of useful details for developers of all levels. I often revisit this book to keep in touch with design patterns that are detailed within. Continue reading Design Patterns – introduction

My name is Mateusz Pustelak, I’m 28 now (time flies :)) and this blog is going to be one of my “pet” projects.

5 years ago I shut down my old blog – mpustelak.pl and for a very long time I have been thinking about writing again. Once, I even installed a new WordPress website and set up all the plugins, however, I wasn’t ready to write anything. Why? I have no idea…
